Abstract: Described in the essay is the manufacturing process flow and the equipment configuration of the Ф530 mm rotary rolling-expanding pipe mill.The rolling cycle(i.e.3 min per piece)of the mill is mainly restrained by the auxiliary rolling time which can be lessened by optimizing the equipment;the measurement/detection components and relative devices are not complete,and thus the intelligentization program needs to be enhanced;and the unstable rolling status of the existing rotary rolling-expanding process also needs to be further optimized.
